Signal Health Practice

Track the metrics that signal change — Nutrition, Movement, Body Composition, Sleep, & Labs — over time.

Everything you record stays on this device. Nothing is sent to a server, and no one else can see it.

Reference ranges

Values outside these ranges are marked in your Laboratory table. Defaults are typical adult reference ranges — edit them to match the ranges printed on your own lab report, since ranges vary by laboratory and assay. Marking a value only means it sits outside the range; it is not an interpretation.

Interpretation

Quick entry and document reading send what you provide — the text you type, or the PDF or image you choose — to be turned into numbers. With a practice code this passes through your practice's service to Anthropic and is not stored along the way; with your own key it goes straight to Anthropic. Either way your health record stays on this device, and nothing is saved until you confirm it. Leave both blank and everything still works — enter data directly instead.

Your data

Everything is stored in this browser alone. Clearing site data, or losing this device, means losing your history. Export a backup regularly. Backup files don't include your API key or practice code, so re-enter those under Interpretation after restoring on a new device.

Signal Health Practice’s tracker is a personal tracking tool. It does not provide medical advice, diagnosis, or treatment recommendations, and does not interpret your results. Discuss laboratory findings and health decisions with a qualified clinician.
